Re: Buster upgrade fails

I just tested that mirror from here, for me it seemed to be working but very slowly.

I have disabled it's entry in the mirror redirection system for now, so if you try again you should be directed to a different mirror.

umm the openscad situation doesn't seem to have changed between stretch and buster, it's not available for armel/armhf because debian builds qt on armel/armhf against opengl es :/

nomanclature for pi4 only add-on boards.

The pi4 has added a bunch of new GPIO alternates. Is there any plan for a naming scheme to avoid confusion between addon boards that are pi4 only and boards that work with all pi models?

Re: Navigating a Raspbian Mirror Site

The raspbian project doesn't currently build any images. The images most people use are created by the raspberry pi foundation and are distributed through their distribution infrastructure. Not through the raspbian mirror sites.

Re: apt stuck on fetch

My prime suspect would be the USB to sata converter in the hard drive case. Apparently there are some converter chipsets that don't get on with the USB controller on the Pi.

Re: I need an import guru

Yes, it's normal. Broadly speaking "import" does two things. 1. Loads modules if they are not already loaded. 2. Binds names so that you can access stuff from those modules. Each module in your program (including the main program itself, which is regarded by the interpreter as a module named __MAIN_...

Re: Introduction to BBC BASIC

This is all very dodgy territory. Turning on optimization should not change the behavior of a program. Except of course if the source is depending on behavior that is undefined by the C standard. Which it is in this case. IIRC the C standard has a massive caveat that even a well-formed program may ...

It's a shielding can. With the raspberry pi 3 model B the board was EMC certified as an end product. That was fine for end-users but it created problems for people wanting to use the Pi as part of a larger product. They essentially had to do the full "intentional radiator" EMC tests again. To make l...

Re: Manjaro dropping ARMv7 support

Such an architecture could certainly be built in theory, but it would require substantially more instructions for every address calculation. Worse, for a modern pipelined CPU those instructions have tight dependencies on each other. Given how cheap transistors are nowadays it makes little sense to w...
